Implementation: Artem Titarenko

This filter increases resolution of video sequence while saving and improving details and reducing artifacts.

Main problems of the current approach:

• Fixed zooming factor (two times). Later it will be generalized.
• No scene change detection.

Characteristics

• Processing speed is considerably higher than for other SuperResolution approaches known to us
• Upscaling factor should be a power of 2. Other scaling factors are also possible, but they result in a relatively lesser quality of video due to use of additional common resampling algorithm
• Different presets with various speed/quality trade-off
• Processing is fully automatic
• Processing can be totally consecutive without look ahead at future frames
• There is a special algorithm for noisy video upscaling which gives smoother images of better visual quality

Examples

Since the output resolution of video is very large only parts of sequences are shown.

The next example is from "news" sequence:

"news", source video and video processed with MSU Super-Resolution filter (video is here, 974 KB)

Fragment of the "toy" sequence:

Public MSU video filters Here are available VirtualDub and AviSynth filters. Commonly we develop a whole family of some kind of a filter. Generally there are also versions optimized for PC and hardware implementations (ASIC/FPGA/DSP). These optimized versions can be licensed to companies.

Also we have internal researches. Please let us know via video(at)graphics.cs.msu_ru if you are interested in acquiring a license for such filters or making a custom R&D project on video processing, compression, computer vision.
